Jan. 1957 1.. v. BENT METAL WINDOW FRAME AND SASH ASSEMBLY INVENTOR.

Filed June 21, 1954 United States Patent 2,775,798:- METAL WINDOW FRAMEAND' SASHIASSEMBLY Leo-V. Bent,.Marcellus','-.Mich. Application June 2'1,,1954,'.Seri'alNo. 438,265 8-Glaiins.- (GI. 20- -55) This invention relates to a metal window frame and sash assemblyincluding a metal frame, desirably of extruded metal, and a combined metal'sash slide and weather strip.

The mainob'jects of this invention are:

First, to provide a window assembly including metal frame and metal sash slide. and weather stripmembers Whicliis well adapted'for use as storm Windowsand including a glazed sash and a sash'provided'with-a screen.

Second, to providea window assembly including an extruded metal'f'rame having a.wayprovided with a dovetailed groove with. which a combined'sash. slide and weather strip. is. slidably, associatedl Third, to provide a. structure havingthese advantages which maybe economically produced andisvvery easily assembled.

Further objects. relatingtd details. and economies. of the invention will'appearfrornthe description tov follow. The invention is defined and: pointecl.out-.in.the claims.

A preferred. embodiment ofjtlie. invention is..illustrated in the accompanying drawing inwhich,

Fig. lis anoutside elevationalfview of.a:window frame having the window assembly of my invention mounted therein.

Fig. 2 is anenlargedfragmentary horizontal section on a line corresponding toline' 22"of"Fi'g. 1.

Fig. 3 is a fragmentary inside view:

Fig. 4 is; afragmentary perspective view of one of the; combinedisash slidesand-Weatherstrip members.-

In the accompanying. drawing I have illustrated my invention as embodied in the storm window assembly. It will be understood that the structure is adapted as the main window assembly in which case the window casing is designed to receive it rather than the frame of the window assembly being designed to be mounted as a storm window assembly on casing of commonly used type.

Referring to the drawings, 1 represents part of a window casing and 2 the outer stop thereof. The frame member 3 is provided with a flange-like extension 4 adapted to be secured to the outer side of the stop 2 by means of screws 5. The frame member 3 is formed of extruded metal and is provided with inner and outer ways 6 and 7 disposed in stepped relation with the outer way 7 having an extending flange 8 on its outer edge. 9 represents a glazed sash and 10 a screen sash, the screen being conventionally illustrated at 11.

The ways 6 and 7 are provided with longitudinally extending grooves 12 of dovetail section. The combined sash slide and weather strip members 13 are of channel section and slidably retained on the ways 6 and 7 by the longitudinally extending dovetailed ribs 14 which slidably fit within the ways and retain the members 13 on the ways.

These members 13 are preferably formed of springable sheet metal stock, the dovetail ribs 14 being formed of off-set folds in the webs 15 of the members 13. The

2: flanges 16 of. the members 131 have inturned edges. 17 which springably. embrace the sides. ofv the. sash members with the edgesof the sash.members in spaced relation to the websof the slide. members.

This forming. of theways with longitudinal dovetail grooves therein and' the forming of the members. 13 with coacting dovetail-ribs 14:slidably retainthese parts in proper relation to. each otherwith the slidessupported onthe ways at both. sidesofthe grooves thereof. This not only serves toslidably support the. members13. but provides aneffective weather.- seal. The formingof the members 13 of slidable sheetmetal stock with .the. flanges springably engagingzthe sides- 012 the sash provides. an effective seal between the. members. 13and: the sashand avoidsthe necessity. of accurate machiningof therparts, and prevents theparts wedging. asa. result of expansion and contraction.

In the embodiment illustrated,.the.frame is represented as. of woodrb'ut. they, mightbe metal, ifdesired. 1- have illustrated my invention as embodied in a storm window assembly. I. have not illustratedother. types of. assemblies as it is believed thatsuch modifications as may be required will. bereadily. understood. by. those skilled in the art. I have. illustratedthe dovetailgrooves andribs as havingJlat outwardly. converging sides; I desire to point out,- however, that=itis practical to form these parts of curved dovetail section,., particularly where. the frame members are of. extruded metal. I have notattemptedto illustrate thevariousother embodiments and adaptations which I. contemplate: as. it. is. believed. that. thisdisclosure will'enable those skilled in theartto. embody or adapt myv invention as. may. be. desired.

Having, thus. described theinvention, what is-claimed to be new and is desired. to be secured by. Letters. Patent is:.

1. In a .window'assembly,.thecombination of aframe member of extruded metal and-havinginner andouter slideways arranged. in .steppedv relation and. havinglongitudinall grooves. therein of, dovetail section, inner and outer sashes, anducombined. sash slide and weather strip members.ofzchannelsectionimwhich the sashes are disposed. with" the. edges. of. the. sashes. in spaced. relation to. the webs ofIthe; channels, said slide. members" being formed of. springable. sheet .metalstock, the arms? thereof springably engaging the sides of the sashes, the web portions of said slide members having longitudinally extending rib-like ofiY-sets disposed centrally thereof and of dovetail section slidably fitting said dovetailed grooves in said ways with the webs of the slide members at the sides of said oil-sets in sliding face to face engagement with the ways at the sides of the grooves therein, the lengths of the grooves of dovetail section being substantially greater than the length of the off-sets of dovetail section to permit the oif-sets to slide longitudinally of the grooves to position the slide members and sashes in different positions longitudinally of the ways, said spacing of the edges of the sashes from the web portions of the slide members and said springable engagement of the arms of the slide members with the sides of the sashes providing an effective weather seal and permitting relative ad ustment of the sashes and slide members in the direction of the width of the sashes to prevent binding of the rib-like off-sets of dovetail section in the .grooves of dovetail section.
